Magnetic part 350 is formed with the annular shape for being inserted into insertion groove 340.Here, due to the thickness of magnetic part 350
H1 is less than the thickness h 2 of insertion groove 340, in the state of before washer 300 is contacted and combined with bolt 100, magnetic part 350
It is attached to the upper side of insertion groove 340, therefore, magnetic part 350 and the bottom surface of washer body 310 are spaced apart.
Why the thickness h 1 of magnetic part 350 is set smaller than to the thickness h 2 of insertion groove 340, is because in bolt
Before 100 are combined with washer 300, general bolt 100 is mixed with washer.
At this point, when multiple washers 300 mix, if magnetic part 350 and insertion groove 340 are with identical thickness
It is formed and is exposed from the lower part of washer body 310, be then difficult to separate the washer 300 being mutually pasted together by magnetic force.
Therefore, washer 300 of the invention is the thickness that the thickness h 1 of magnetic part 350 is set smaller than to insertion groove 340
H2, so as to magnetic part 350 with it is spaced apart below washer body 310.Therefore, as shown in Fig. 4 (b), even if multiple
